Patented Sept. 26, 1933 This invention relates to an improved form ofmixing device and relates to the same general subject matter asdisclosedin my pending application, Serial No. 420,570, filed January 13, 1930.

i 5 Although the present device is intendedespecially for the mixing ofsoap and water into suds for use in connection with-the cleaningof-autoe mobiles, etc., yet it is to be understood that the v inventionas herein set forth comprehends any l0 and all uses to which this formof structure may be put; as for instance in the mixing of othermaterials. q j

In the use of devices of this same general nature, it has been foundthat insome localities, the pressure of the water in the municipalsupply system is so great that it is not'well, adapted for directapplication to a body of soap. Suchexcess pressure of the water as itimpinges upon the body of soap or other material within the container,causes too rapid consumption of the same and an improper combination .ofthe soap and water 'ior'the consistency of mixture.

'It is therefore the object of the present invention to devise anadjustable means for relieving thepressure of the water supply so as toreduce the force of the same as it impinges 'upon the soap and therebyobtain the proper dissolving action of the water upon the soap as wellas the proper consistency of mixture.

Other objects will appear fromthe following description and claims whenconsidered together with the'accompanying drawing. Fig. 1 is ay'planviewof my present improved form of device; and Fig;;2'is a sectionalView taken on line 2 2 of Fig. 13 Y It' isto be understood that thepresent disclosure is merely'foripurposes of illustration and that theremay be devised various modifications without departing from the spiritofthe presen inventionas herein set forth and claimed. g The. container 1is provided with the false bottom 2 so as-to provide a mixing chamber3'beneath the same. 'The'bottom 2is provided. with a centrally disposedopening, and the vertically arranged perforatedtube 4 isconnect edto theopening so as to afford communication through the tube 4 and into thechamber 3. The tube 4 may extend throughoutthe entire'height of the oftheitop thereof or may terminate a short distance below the same. Y

In the present form of structure, the upper end of 'the #bolts G'theremovable centralportion '7- which has the centrally disposed chamber 'lbelow-the same. Around the lower outer edge'of the-wallof chamber 7thereare provided a secontainer l that is, so as toengage the under sideries of spaced, annularly disposed openings which permit passage ofwater or other fluid out-F wardly therethroug'h into the space'betweenthe body. lof thecontainer and the tubular member 4'. This space isoccupied byisoap o'f ,propercon sistency which is dissolved by the waterand carried through the openingsof tube 4.) I

upwardly The central part' 7 of the top has an extending screw-threadedprojection 19th which may be attached a valve casing 10 for supplyingwater-to the chamber 7 The valve casing 10 I is of tubular form soas topermit passageof water or other fiuid'therethrough andhas its upperend Yscreweth'readed atilO for attachment ofa' hose or other means of:connectionirom-the source of water supply. The apertured .web portionprovides aseat for the valve 11 which normally occupies closedpositiontherewith by virtue ofthe coil spring 12 surrounding thevalve'stem' This valve may be opened, however,- by turning the handle 13about the axis. oi the valve stem I w and while maintainedlin-suchposition, therewill be permitted a flowof water or other fluid hrough,the tubular casing l0, into theichamber 57 and thence through theopenings lafinto the compartment occupiedby the soap. .Upon release ofhandle 13 and closing of thelvalvertheimixing op:

eration as well as the discharge of suds from the mixing chamber willcease. Any fiu'id which might then drain from the upper part of the de-Y vice will be held within the. mixing chamber. The. Y particular typeof valve, hereinldisclosed is old and well known and does not enter thepresent invention, except insofar as: it serves as a means for openingand closingthe passage through, the

tubular casing 10. ,Any other suitable form of valve may be employed forthis same purpose and.

in this same combination.

, Through the center ofthe bottom wall. of,

chamber 7%, there is an ap'erture over the lower side ofwhich is appliedthe-casting 14.. This casting has a tapering bottom which is pro-.

vided with an opening therethrough. This ;cast-' ing is provided alsowith a transverse web-portion 14 in which is mounted an adjustable'screw plug closure 15 which has its lower end tapered r. a

for engagement infthe tapered edge of 'the' open-j ing in the bottom ofthe castingl4. This cast-xing is screwed to the under side of thewall 7as indicated in the'drawing. r The upperend of the screw plug 15 isprovided witha slot 1 5 for engagement by a screw I driver for adjustingthe plug to the desired position 7 so; as .to vary the degree of fluidwhich is permitted to "pass through. the opening in the bottom of thecasting'l4. In this way, the pressure. through the holes 8 can be moreor/less relieved and the water which is permitted to pass through theOpening in the casting 14. will pass directly'into and through the tube4' and :thence into the mixing,

chamber 3 where the suds are formed by the churning action which theretakes place. As illustratedinl ig. 2, the upper end. of the tube 4engages about the central depending flange portion provided about theopening through the bottomof chamber 'l In'actual practice, when thepresent form of device is adopted for use in a given locality, the screwplug will be set so as to relieve to the proper degree any excesspressure inthe water f supply lineand thereby obtain the proper'degreeof pressure through the openings 8.; Access may "be readily had to theupper 'end'of the screw plug 15 when the valve casinglO is removed fromthe topjoi the container. This device is then condition,forbohtinued usein spite of the exessive degree'oi pressure in the main supply line;Ifthe pressure in any given supply line should warrant,the plug may beclosed entirely, so that the present form of device is capable ofuniversal application in all communities.

The goose-neck 16' is provided in the side wall of themixing chamber 3for discharge of the mixtureofflsoap and. water or other ingredientstherethrough. This goose-neckwill be of substantially the same formherein disclosed and win be attached at'approximately the 'sanie'point'withrespectto the depth of; the mixing cham;

ber 3, as indicated in Fig. 2 of the drawing The screw'plug l'ifclosesanopenihgthrough the wall 1 just above the false bottom 2, and uponremoval or this plugyit'ispossibleto ascertainthe neces ,sity' ofreplenishing the supply of soap Within the container. g

Thus, I have devised an" apparatus with means of adjustment whereby theproper degree of pressuremay. be supplied to thebody of'soap within thecontainer: and any excess pressure of the mainline relieved. In thisway, there may be obtained the proper dissolving action of the waterupon the soap, while the water which is permitted to flow directlythrough the tube 4 l will serve to mix with the soap solution in the 1chamber 3 so as toqform the proper degree of" Thus, there is ob-' taineda proper balance betweenthe water which consistency in the mixture.

passes directly through the tube 4 andthemixture of soap and'waterproducedby the dissolving action .of the water which is .permitted topass throughthe openings 8. The result is that there is obtained in themixingchamber 3, thedesired'consistency of suds and at the Sametime,

.the dissolving action is produced in a most effi- V 'cient manner, inspite of theprevailing excessive pressure in the water supply line.
